SNMP Traps Translate

[Yevgeniy Semerikov]

Hello!

I'm use zabbix_trap_receiver.pl for deliver SNMP traps to Zabbix. It's works fine, but after I'm add MIBs to net-snmp i get partially translated data.

In /var/log/messages I'm see:

Jun 10 11:51:02 host snmptrapd[23121]: 2014-06-10 11:51:02 localhost [127.0.0.1] (via UDP: [x.x.x.x]:48107->[x.x.x.x]) TRAP, SNMP v1, community ZBX#012#011ADIC-TAPE-LIBRARY-MIB::logicalLibraryStateChange Enterprise Specific Trap (17) Uptime: 61 days, 0:48:01.06#012#011ADIC-TAPE-LIBRARY-MIB::logicalLibraryState.1 = INTEGER: onlinePending(2)

But, zabbix_trap_receiver.pl produces translated OID, but untranslated value (see ADIC-TAPE-LIBRARY-MIB::logicalLibraryState.1):

Anyone know how to fix it?

[Yevgeniy Semerikov]

Solved. Simple Perl function SNMP::mapEnum($oid, $value).

Can you explain how did you fix this? I have the same problem here

Just add or replace some lines in zabbix_trap_receiver.pl by:

if ($translate = &SNMP::mapEnum($oid, $value)) {
$value = "$type: $value ($translate)";
} else {
$value = "$type: $value";
}

Can you post your zabbix_trap_receiver.pl code here? I'm don't know perl programming so I'm kinda lost

Thank you very much! Solved.

Hello guys,

Is this still working with net-snmp-5.8? We get no translations for already mapped oids to names by snmptrapd. As we generate keys in mib2zabbix with the oids ( $item->{ key } = "snmptrap["\\s$oid\\s"]" ), snmp traps match fails for hosts in zabbix.

(I found something similar here: https://archive.gwos.com/groundwork-.../snmptt/snmptt and it could explain...)

Thanks.

[kabassanov]

OK, I confirm that &SNMP::mapEnum does not translate oids (anymore?). But &SNMP::translateObj does it. So just need to define which kind of entries have to be translated. IMHO, snmpTrapOID is enough...

Patch below has tested on 5.4 version zabbix_trap_receiver.pl, add it on line 104 inside foreach my $x (@varbinds) and before the printf inside the loop:

my $oid = $x->[0];
my $value = $x->[1];
$value =~ m/^([\w-]+): .+$/;
$type = $1;
$value =~ s/$type: //g;
if ($translate = &SNMP::translateObj($oid, $value)) {
    $value = "$type: $value ($translate)";
} else {
    $value = "$type: $value";
}
